(effect)
Then, use Fig. 6, the effect of endoscope 3 is described.
As shown in solid line in Fig. 6, when lifting platform 51 and being in inversion state, if insert the treatment tool TD1 such as sleeve pipe from forceps channel 25b in channel C H1, then treatment tool TD1 top ends via in channel C H1 after peristome 31a stretches out, first bearing surface 51c is connected to, afterwards, move along bearing surface 51c to the direction of top ends 51b.If be pressed into treatment tool TD1 further in forceps channel 25b, then the top ends for the treatment of tool TD1 exceedes the top ends 51b lifting platform 51, and further exceeds the protuberance 34 between peristome 44 and ultrasonic transducer section 33, gives prominence to from peristome 44.
Treatment tool TD1 now gives prominence to from peristome 44 with angle θ 1 relative to the top orientation of the insertion axis C0 of insertion section 11.Angle θ 1 is by the High definition of the elasticity for the treatment of tool TD1 self, the position of peristome 31a and the protuberance 34 as abutting part.In the case of fig. 6, because the side for the treatment of tool TD1 contacts with the some P1 of protuberance 34, therefore angle θ 1 is roughly limited with the position of putting P1 by the position of the treatment tool TD1 at peristome 31a place.
And as shown in solid line in Fig. 6, when lifting platform 51 and being in inversion state, if insert the treatment tool TD2 such as sting device from forceps channel 25a in channel C H2, then the top ends for the treatment of tool TD2 moves along the inwall of channel C H2.If be pressed into treatment tool TD2 further in forceps channel 25a, then treatment tool TD2 top ends via in channel C H2 after peristome 31b stretches out, can not encounter and lift platform 51, but give prominence to from peristome 44.
Treatment tool TD2 now gives prominence to from peristome 44 with angle θ 2 relative to the top orientation of the insertion axis CO of insertion section 11.Angle θ 2 is limited by the inner wall shape of the channel C H2 near the elasticity for the treatment of tool TD2 self, the position of peristome 31b and peristome 31b.In the case of fig. 6, because the side for the treatment of tool TD2 contacts with the some P2 of peristome 31b, therefore angle θ 2 is roughly limited with the position of putting P2 by the position of the treatment tool TD2 at peristome 31a place.
In addition, at this, treatment tool TD1 forwards gives prominence to angle θ 1 relative to the top orientation inserting axis CO, this angle θ 1 by the High definition of the elasticity for the treatment of tool TD1 self, the position of peristome 31a and protuberance 34, but also can reduce the height of protuberance 34 or raising lift top ends 51b when platform 51 is inverted, contact to make treatment tool TD1 the top ends 51b lifting platform 51 apart from the height of the bottom surface of recess 45.In this case, angle θ 1 is by the elasticity for the treatment of tool TD1 self, the position of peristome 31a and the High definition of top ends 51b, and treatment tool TD1 does not contact ultrasonic transducer section 33.
In this case, in figure 6, the side for the treatment of tool TD1 does not abut against with protuberance 34, the some P5 place of lifting the top ends 51b of platform 51 shown in dotted line, the side for the treatment of tool TD1 with lift platform 51 and contact.
